92 HISTORY OF PERSIA The Ziyand Dynasty^ A.H. 316-434 (<)28^04;*).~ During the reign of Nasr II. the province of Tabaristan was recovered for the House of AH by Hasan bin Ali- Utrush, but a few years later, in A.H. 316 (928), a certain Mardawij bin Ziyar contrived to seue it and to occupy Isfahan and the country beyond ! lamndun as far as Holwan. He established a dynasty which was noted for its devotion to learning and which endured for rather over a century, although no member except its founder played a leading rcMe on the stage of Persia, The best known of his successors was Kalnis, A.H. 366 • 403 (976-1012), the patron of Al»biruni> who dedicated to him his famous Chronology of .'hicitM Ntithm and resided at his court for many years. Nor was he merely a patron of letters : he was himself a poet of no mean order, writing both in Arabic and in Persian.1 In the latter language he composed an exquisite quatrain, translated as follows : Mirth's King the Rose is, Wine Joy's Hcttthl eke ; Hence from those two do I my pleasure st*ek ; Would'st thorn, 0 Moon, inquire the cause of this ? Wine's taste thy lips recalls, the Rose thy cheek ! The career of Kabus was extremely chequered* F Ic protected Fakhr-u-Dola, one of the Bu way hid princes, against his two brothers, the powerful Azuu-u-Dola and the Muayyid-u-Dola, and in consequence was driven out of his princedom for many years. Upon his return, although he was famed for " his learning, piety, munifi- cence, magnanimity, wisdom, prudence, and intelligence,"8 his nobles, exasperated by his cruelty, deposed him urn! afterwards had him secretly murdered, In 1908 I visited his tomb, which, as Ibu lafiuutiyar states, is "outside Gurgan on the road to Khorasan." As the ^lustration shows, it is a lofty decagon with a curious conical roof, which is visible for miles across the level steppe.
